Name: _____________________ Marine Science Date: ____________________ Mr. Micciche Aim: How can we understand food chains in a marine environment? Do Now: MOOD – Killer Whale HW: -Food chains represent ____________________________________________________. -If the arrows point from the frog to the snake, what does that mean? ________________________________________________________________________ *How do Food webs differ from Food chains? ________________________________________________________________________ *Why is the Sun considered the ULTIMATE SOURCE OF ENERGY? ________________________________________________________________________ ________________________________________________________________________ Sun Phytoplankton Krill Herring ALL OTHERS -There was an “algal bloom” due to _________________ because of the changing of the seasons and the increase of sunlight. The Phytoplankton provide energy directly to the ________ which then provide energy to _______________. -This species takes advantage of this time to reproduce, leaving a huge scum on the surface of the water made of _______________. Name: _____________________ Marine Science Date: ____________________ Mr. Micciche -Due to the high volume of Herring, three other species migrated to feed: ________________________________________________________________________ The Black Patches of the Ocean -These black patches were actually caused by the extreme volume of ________________. -This migration was caused by a change in current. Another example of how currents affect the distribution of nutrients and life. -The black patches attracted birds, sharks, dolphins, and eventually a whale. *Why was the presence of the dolphins good for the birds? ________________________________________________________________________ Whales v. Whales -The Grey Whale has ______________ in its mouth to help catch krill. The calf of a whale has an incubation period of about 15 months. Mothers actively supervise young. -The Killer Whale, also known as ____________, actually hunts other whales. *How were the Killer Whales able to kill the young calf? ________________________________________________________________________ ________________________________________________________________________ -The dead carcass of the whale eventually sank to the bottom of the ocean. The jawless species known as _______________ fed on the whale. -The jawless fish are equipped with ___________ teeth to shred meat. -They were eventually joined by the sleeper shark. How did it get its name? ________________________________________________________________________ ________________________________________________________________________
